+### Interacting with the proxy
+
+#### Changing the owner
+
+The proxy owner is able to set the address of the implementation contract.
+To change the proxy owner you can call this function from the current proxyOwner:
+
+```
+    function setProxyOwner(address _newOwner) onlyProxyOwner public;
+```
+
+### Updating the implementation
+
+To change the implementation contract you can call this function from the proxyOwner:
+
+```
+    function setImplementation(address _newImplementation) onlyProxyOwner public;
+```
+
+### Considerations when upgrading implementations
+
+When using a diamond standard contract often its not needed to upgrade the diamond but the upgrade can be carried out through upgrading the diamond facets.
+
+When upgrading a "normal" contract you have to make sure to only append to the storage vars to not corrupt storage. Changing the inheritance can corrupt your storage.
